Abstract
An air distribution unit for discharging conditioned air into an area to be conditioned and having a plenum chamber for receiving conditioned air and an outlet in communication with the plenum chamber and with the area being conditioned. A damper is employed to regulate the flow of conditioned air from the plenum chamber to the outlet with the damper being responsive to a thermostat to regulate the quantity of air discharged into the area in accordance with the temperature requirements thereof. The distribution unit includes an override control to maintain the flow of air through the damper at a constant predetermined rate irrespective of the temperature requirements in the area, the override control becoming operable when the damper has initially discontinued flow of conditioned air into the area in response to sensed temperature.
